Libre and Medtronic 780G are completely different things.
@james555 have you tried contacting Medtronic?
With a quick Google search, I found this https://guardianconnect.medtronic-diabetes.co.uk/app-compatibility but this is only the CGM. I found nothing with regard to pump compatiblity.
That said, it was only a quick search and I did notice the pump manual is online which I didn't bother reading.
Good luck. Looks like it may turn into a closed loop system if the CGM part (Guardian)can be funded by the NHS in which case it will work with any Samsung smart phone with blue tooth but you should be able to ask the pump rep. In my case (tandem pump with dexcom) I can only see my bg results on my phone rather than pump data so would be interested to see what yours can do!
Hi james555.... If you just Google medtronic 780g compatible phones you will see a full list available. My young daughter has a Samsung S10 for hers. We're Ireland also and she's been on the 780g since the summer and has changed her life (and mine) for the better... Best of luck on your new journey
Thanks very much glad you and your Daughter is getting on well with your new pump put mine on on last Friday won't be going in to Auto mode on till 29 so looking forward to that and I am lucky my Samsung 21s is working with pump thanks again
